A small ball is attached to one end of a spring that has an unstrained length of 0.222 m. The spring is held by the other end, and the ball is whirled around in a horizontal circle at a speed of 3.79 m/s. The spring remains nearly parallel to the ground during the motion and is observed to stretch by 0.0128 m. By how much would the spring stretch if it were attached to the ceiling and the ball allowed to hang straight down, motionless

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
